Technical resources

Supporting your preparation

The technical resources are provided to support your firm’s preparation for the new digital services.

Please share a link to this page with the relevant people in your firm and with any external vendors and service providers.

Technical resources will include the EDI schedule and technical specifications, the API schedule and how to access the specifications, as well as any other technical artefacts that are produced as the programme moves through the build of the London Market solutions. The EDI and API specifications will be issued over the coming months so please check back for updates.

Update 29 March 2023

On 29 March 2023, we published the remaining seven EDI technical specifications marked for release in March. This concludes the activity on releasing EDI technical specifications as set out in the EDI release schedule.

Please note:

1. EDI technical specifications CLMLRC and CLMILC have been split into separate documents for brokers and carriers. This is shown in the table below and a note is added to the introduction in each technical specification.

2. LORS Appendix A has been added to the table below. Additional appendices will follow by close of business Thursday 6 April.

All EDI technical specifications issued are final versions at the time of publication and vendors are able to use these to make any amendments required to be able to produce or consume the new EDI messages.

We are mindful that the overall programme is being run on an agile basis so there remains a slight risk that the specifications may need to alter to align with the build of the digital processing services. We would stress:

Change is not expected.
Change will only happen if the specification needs to be updated to deliver the functionality in the new digital processing services, and these will be minor.
Any change will be notified as soon as possible.

The above applies to standard EDI messages which are represented by all technical specifications referred to in the release schedule and published. If vendors and/or clients are using bespoke EDI messages then the impact of any change will vary depending on how the message has been altered.
